In this paper, a fractional-order model of hepatitis C virus (HCV) with inhibition due to infection is studied. Based on the basic reproduction number, backward bifurcation of such model is investigated under some conditions. When the efficacy of interferon-α therapy is low, it is shown that the phenomenon of backward bifurcation will appear in the model. It means that there coexist disease-free and...
In recent years, human resource recruitment websites have been more and more popular in the talent market. The HR recruitment website is an important part in the E-business world. Several HR recruitment websites in China have been in a leading position in this field. In the mean time job hunters find it difficult to assess those websites for their choice decision. This paper utilizes Analytical Hierarchy...
In this paper, a class of fuzzy cellular neural networks with mixed delays is studied. By using the fixed point theorem, M-matrix theory and some analytic techniques, sufficient conditions for the existence and global exponential stability of the unique equilibrium point are obtained. For illustration, an example is given to show the effectiveness of the obtained results.
A nonlinear control system that integrated active front steering system and vehicle dynamics control system based on a multi-body vehicle dynamic model is introduced in this paper. The multibody vehicle dynamic model based on ADAMS can accurately predict the dynamics performance of the vehicle. The control strategy consists of two control objectives (yaw velocity omega and sideslip angle beta). An...
